"WebMy first way is thus: F = m a, so a = F / m, the initial acceleration ( or should that be ( F − f) / m ?). And then the deceleration is a = − f / m. I'm not sure how to calculate the initial linear velocity, but assuming I have it, u, say, then I could say that after time t the velocity is v = u − a t = u − f t / m, where f is the friction force.

WebNov 15, 2013 · When an object passes through a fluid, the force of decelleration increases with speed, so the faster the object the greater the drag. As the object slows down, decelleration grows weaker, and the object keeps slowing down but never stops. This describes a globe spinning in air or water.
